This is especially effective in species whose wild diet includes birds. Reptile Lighting Information Information on how natural and artificial lighting affects reptiles. These lamps are characterized by fairly low intensity visible light and little heat.

Large prey is dragged to the bottom of the water, drowned while pieces of flesh are twisted off and bolted. The teeth of the tuatara, snakes and many lizards are found in the upper and lower jaws and additionally often on the palatal bones, these are used exclusively for grasping the prey. Venomous snakes have specialized teeth for envenomating prey. Opisthoglyphs, or rear-fanged snakes, have grooved teeth on the back of the upper jaw.

These snakes cannot inject their prey by merely striking but must chew their victim to introduce the venom. Solenoglyphs vipers and proteroglyphs cobras etc. With these teeth the venom secreted by the venom gland parotid gland is injected into the victim's flesh. The venom quickly immobilizes and then kills the prey, and only at this point is it swallowed. On the other hand, those snakes which lack grooved teeth aglyphous species , often immobilize their victims by constricting them in their coils and after suffocating them, swallowing them head first.

Both types of snake, however, are able to expand their mouth enormously in order to swallow thanks also to the large, extensible esophagus prey of considerable dimensions. When kept in captivity many of these snakes will consume frozen feeder mice or feeder rats depending on their size.

Crickets escaping into the house or dying in large numbers due to disease can cause savings to quickly dissipate.

Many herpkeepers find it more convenient to drive to their local pet store to purchase them. We keep our crickets in 5-gallon buckets or small trash cans depending on their size. It is vitally important to keep these food items warm; crickets have a much lower survival rate if they are not maintained at a minimum of 75 degrees Fahrenheit.

Temperatures should range from 75 to 95 degrees, but it is best to keep changes within that range as narrow as possible. Several methods can achieve the appropriate temperatures. A low-wattage incandescent bulb or ceramic heat emitter can be suspended over the enclosure, but take care not to let the insects jump onto the heat source, which may facilitate escape or cause thermal burns.

A digital thermometer can be used to find the optimal distance from the top of the enclosure to the heat source. Heat pads placed underneath the enclosure also maintain adequate temperatures. Feeding crickets a proper diet is critically important both for the health of the crickets and for the animals eating them.

Cricket diets can be purchased online and found at most pet stores. Adding squash, carrots, sweet potatoes and some mixed greens to this base diet is important for providing other nutrients and moisture. Offering fresh food items on a daily basis ensures the proper health of the crickets, and removing uneaten food items is helpful in reducing the odor associated with culturing crickets. Mealworms Tenebrio molitor are also a great food item for many insectivorous reptiles and amphibians.

One mealworm contains several times the caloric content of a single cricket. Thus, feeding your herp mealworms helps to maintain its body mass. One drawback of mealworms is their thick, chitinous exoskeleton. Secondary to the difficulty in digesting these insects, overfeeding mealworms often causes regurgitation in herp pets. Feed the worms to herps in moderation.

Mealworms can be purchased in bulk and are easily maintained in a 5-gallon bucket. The substrate should consist of wheat bran, and moisture can be provided in the form of potatoes, carrots and occasional leafy, green vegetables. Again, remove uneaten food items to reduce the smell associated with culturing these insects. In the past 15 years or so, the king mealworm Zoophobias spp. These larger mealworms are popular because they are more conspicuous movers and often a more appropriate size for larger insectivorous reptiles.

Several companies offer cockroaches for insectivorous herps. These insects are easily reared in plastic tubs, and most of them do not require substrate. Like crickets, cockroaches require warmer temperatures for optimal production.

Keep them at temperatures around 75 degrees. Many species of cockroaches, such as lobster roaches Nauphoeta cinerea , can climb smooth surfaces, including glass, so extra precautions must be taken to ensure that the enclosure is escapeproof. Several products can be smeared along the top lip of the enclosure to prevent escape. Vaseline is the cheapest product to use.

Simply place a 1- to 2-inch strip of Vaseline along the top of the enclosure. A number of cockroach species do not climb glass. One such species is the orange-headed roach Eublaberus posticus. Although this species does attain a larger size, the instars the stage between molts are of an appropriate size for many species of lizards and frogs.

Culturing cockroaches has significantly cut down on our monthly cricket bill, and despite our initial disgust at the thought of raising these insects in our home, they actually have a number of benefits over crickets. These benefits include decreased odor production, a reduced chitin-to-meat ratio, and in some cases more conspicuous movement.

Silk moth larvae Bombyx mori can also be acquired via several online resources. Vendors typically have them at reptile expos, as well. Silkworms can be maintained on a diet of mulberry leaves, and a mulberry leaf powder can be reconstituted to feed the worms during the winter months. A simple plastic container works well to maintain a group of these worms. Depending on how much they are fed and the temperatures at which they are maintained, these worms can grow very quickly and to a large size.

Keep them at a temperature range between 70 and 85 degrees, and they will do well. Mulberry leaves have a high mineral content, so silkworms make a nutritious food item and can be an excellent source of calcium. Easily reared, they are relatively inexpensive if raised from a small size or egg.

Like silkworms, tomato hornworms Manduca quinquemaculata can be picked up from a variety of online sources. However, do not use wild-caught tomato hornworms because these may be toxic to your insectivorous herp. Only purchase these worms from a vendor where you can be assured they were raised on a nontoxic diet and are safe for your herps to eat.

Tomato hornworms are sold in large deli cups with the appropriate food. In this setup they grow quickly and thus must be used in a timely manner, usually within a few weeks. Tomato hornworms weigh up to 12 grams, so they provide many more calories than crickets. These worms are especially helpful for reptiles and amphibians that need to put on a little weight, such as anorexic animals, those that have been ill and are recovering, or those that are ready for breeding.

A rodent colony can be extremely helpful in reducing the cost of maintaining a large group of snakes or large carnivorous lizards. Like culturing feeder insects, rodent husbandry is very important in ensuring a healthy food item for your captive. The principle consideration when maintaining a rodent colony is cleanliness.

Change the substrate at least once a week. Sometimes twice a week is better, such as during periods of heavy breeding. Rodent breeding typically slows down during the winter months, which can present a problem if you are feeding reptiles and amphibians that are active year round. Plan accordingly and try to have a number of frozen food items during these months. You can purchase these or cull them from your livestock during periods of higher production.

Another consideration in rodent production is the frequency in which producing adult mice should be culled. Ideally, older mice should be fed to pets roughly every two to four months. The final component to successful rodent maintenance is diet.

Several companies manufacture rodent blocks specifically for mice, rats and other rodents.
